RepairPal has identified the most common problems with the Scion xB as reported by actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.

An illuminated Check Engine Light could be caused by a defective VVT-i controller, which changes cam timing for optimal power. Updated parts are available and the repair may be covered under the powertrain warranty.

When backing up and applying the brakes, you may hear a squeaking noise. Scion engineers addressed this problem by modifying the shape of the brake pad and the anti-squeal shims; they also applied more grease during assembly.

Vehicles fitted with remote start may encounter a dead battery after sitting for a few days. This can be due to a parasitic draw caused by the remote start computer. Our technicians remind us proper diagnostic procedures should be followed before replacing the remote start module with an updated part.
